I have always wondered why the add a CP3 was all I saw for the 6.7 but figured some kind of technical issue prevented dual CP4. In Diesel Power this month they have a 2012 6.7 with dual CP4.2s so now I wonder again......why don't you see these in the market place? I have a CP4 laying in the garage so I'd save the cost of the second pump.
